CHURN.

SPECIFICATION forming part of Letters Patent No. 417,310, dated December 17, 1889. Application filed February 13, 1888. Serial No. 263,927. (No model.)

To all whom it may concern:

Be it known that I, Monnis N. CASTLEMAN, a citizen of the United States, residing at Rockford, in the county of \Vinnebago and State of Illinois, have invented certain new and useful Improvements in Revolving-Barrel Ohurns, of which the following is a specification.

This invention relates partly to the form to and construction of the open end of a churn and partly to the manner in which the cover is secured thereto.

The object of this invention is to produce a revolving churn'the aperture whereof is so :5 formed and constructed that therethrough ready and complete access may be had to all parts of the interior thereof.

A further object of this invention is to provide an improved means of securin g covers to revolving churns.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is an isometric View of the upper portion of a churn provided with my improvements.

Fig. 2 is a viewof a verticalsection of the up per portion of the churn through the dotted line a: .r of Fig. 1. Figs. 3, i, and 5 are isometric views, in detail, of parts of the eh urn illustrated in Fig. 1, and will be fully described hereinafter. Fig. 6 is aview of a detached portion of Fig. 2.

Like letters of reference indicate corresponding parts throughout the several views.

A represents a revolving-barrel churn having a croze A in the end thereof.

A represents an annular recess formed by removing the entire inner portion A" of the chine A" of the churn A.

B represents a chine-ring of proper form and dimensions to be seated in the annular recess A and t9 be included therein, so as not to project inward beyond the inner surface of the churn. in the chine A, and having a horizontal annular flange B adapted to enter the crew A therein, and a vertical annular flange B projecting above the chine thereof.

C represents a removable churn-cover, circular in form and provided with a semi'rectam gular peripheral groove O, which contains cork O or other suitable elastic packing designed to engage and form a tight joint with the annular flange B of the chine-ring B.

D represents a metallic casing that completely incloses the periphery and upper peripheral angle of the cover O.

D represents retaining lugs projecting from the casing D.

E represents an arm provided with an incurving hook E, adapted to engage with the lugs D of the casing D, and having a vertical slot E extending through the lower portion thereof, and a short horizontal stud E proj ecting outward therefrom.

F represents a boss having a vertical slot F in the outer face thereof and provided with o 5 a horizontal pintle F which projects outward from the center of the slot F.

F represents holes in the boss F, through which bolts are passed to secure the same to the churn A.

F represents a pin-hole in the pintle F Gr" represents a cam having acircular opening G therein and provided with a handle G and a slot or groove G.

G represents a pin-hole for retaining the cam G upon the pintle F After the bosses F have been bolted to the churn, the slots F therein being vertical, the pintles F are inserted through the slots T2 in the arms E and the openings G in the cams G, and the studs E are made to engage with the slots G of the cam. Next revolve the cover 0 until the lugs D pass under the hooks 1. Depressing the handles G of the cams Gr forces thearms E downward, and the hooks 8 5 E are thereby caused to descend and secure the cover to the churn. A reverse motion of the handles Gr releases the cover 0.

The ring-head heretofore used to connect covers with revolving churns is inconvenient 9c and unsatisfactory in several important respects. In the first place the ring-head prevents commodious access to the interior of a churn by diminishing the diameter of the aperture leading thereinto one-fourth to onethird; second, it presents a serious obstacle to the removal from the churn of its contents; third, its use renders it difficult to properly cleanse the inside of the ring-head and that portion of the interior of the churn adjacent roo thereto, and, fourth, its employment makes it necessary to attach a heavy compensating Weight to the bottom of the churn to balance the same.

All the disadvantages above enumerated are completely avoided by using a chine-ring like the one herein shown and described in lieu of the ring-head heretofore generally used in the construction of revolving churns.

By employing the cams and attachments shown greater and more evenly-distributed retaining force can be applied to churn-covers than in any other practical manner.

1. The combination, with a rm olving-barrel churn having an annular recess therein along the entire inner portion of a chine thereof, of a chine-ring seated and included in theannular recess and provided with a vertical annular flange projecting above the chine of the churn, substantially as described, and for the purpose specified.

2. In combination, an arm provided with an incurving hook having a vertical slot extend-' ing through the lower portion thereof and a horizontal stud projecting outward therefrom, a boss having a vertical slot in the outer face thereof and provided with'a horizontal pintle projecting outward from the center thereof,

and a cam mounted on said pintle and engaging with and operating the said arm through the medium of the aforesaid horizontal stud, substantially as set forth.

3. The combination of a churn, a removable head, and a chine-ring fixed in the churn, said chine-ring fitted with a projection to enter the croze and extending upward along the interior of the churn and extending above the chine of the churn to receive the removable head, substantially as set forth.

v at. The combination of a churn, a removable head, and a chine-ring, said chine-ring fitted with a projection to enter the croze and extending upward along the interior of the churn and extending above the chine of the churn to receive the removable head, and means for securing the removable head to the chine-ring, substantially as set forth.

5. The combination of a churn, a removable head, and a chine-ring, said churn having an annular recess therein along the entire inner portion of the chine thereof, said chine-ring seated and included in the annular recess and provided with a vertical flange projecting above the chine of the churn to receive the removable head, and means for securing the removable head to the chine-rin g, substantially as set forth.
